A small model earth pressure balance (EPB) tunnel boring machine (TBM) will be designed that can simulate excavation similar to real on site tunneling. Monitoring will be done using acoustic emission (AE), borehole extensometer, strain gages and accelerometers will be installed in TBM and on the cubical specimen. The critical conclusions and correlation developed from the experimental results will contribute significantly and will be give better insight into the problem of tunnel squeezing.]]> Fri, 16 Feb 2018 19:26:13 GMT https://rip.trb.org/View/1500818 Investigation of Multimodal Surface Transportation Infrastructure Asset Interactions Using Acoustic Emission and Other Non-destructive Testing Technology Tools https://rip.trb.org/View/1286860 Thu, 23 Jan 2014 01:00:28 GMT https://rip.trb.org/View/1286860 Short-Term Evaluation of a Bridge Cable Using Acoustic Emission Sensors https://rip.trb.org/View/1231814 Thu, 03 Jan 2013 14:26:38 GMT https://rip.trb.org/View/1231814
